Parent的构造出设置断点即可

Parent...static-statement-block

Child....static-statement-block

Parent..........statement-block

Parent..............constructor //Child.<init>() line: 6--> Child(Parent).<init>() line: 5

Parent..........statement-block

Parent..............constructor //Child.<init>() line: 5--> Child(Parent).<init>() line: 5

Child...........statement-block

Child...............constructor //Child.<init>() line: 7

package com.wnj;public class Child    extends Parent {    private Parent p = new Parent();    public Child() {        System.out.println( "Child...............constructor" );    }    {        System.out.println( "Child...........statement-block" );    }    static {        System.out.println( "Child....static-statement-block" );    }    public static void main( String[] args ) {        Child c = null;        c = new Child();    }}

package com.wnj;public class Parent {    public Parent() {        System.out.println( "Parent..............constructor" );    }    {        System.out.println( "Parent..........statement-block" );    }    static {        System.out.println( "Parent...static-statement-block" );    }}
